Dangerous vs. Safe batteries, Explosion and fire test!

Li-Pol (LiPo) batteries are widely used in nearly all Cell phones and other home electronics. Yet, they are unstable and dangerous. In our test, we compare LiPo with available LFP and LTO technologies.
You may not recognize the danger of sitting in your pocket, but consider the danger for projects involving batteries and prevent future issues. Designing a machine, device or tool that uses batteries? Choose wisely!
All tested batteries are based on lithium, however, the additional substances in LFP and LTO provide necessary stabilization and prevent dangerous behaviour.
Are you wondering how toxic is that smoke? This we've measured in this episode: • How toxic are the Lith...

safety and energy density is always a engineering tradeoff. most of the more volatile chemistries are perfectly safe if treated right. but there is something to be said about using inherently safer chemistries for alot of applications.

[@kadragon3764]

Exactly. Li-PoL are very common because of their form factor compared to that of the others. You may say that they're super dangerous, but that's if you're excluding modern circuitry that commonly comes with said batteries effectively eliminating almost all of the risks. Similar way to Nuclear Power in a way. It is arguably one of the cleanest and most efficient energy production methods. Modern plants have many safety features making a meltdown very very unlikely. But due to it being also one of the most horrible disasters if it does go horribly wrong, a few accidents have put a bad taste in many people's mouths.

[@BloPsy__]

@Stratos Fear Nuclear power is safe if you follow proper guidelines too :) Jokes aside, nuclear power is the most efficient source of energy right now and also one of the cleanest at the same time. Sure there is nuclear waste, but there are reactors in development that can use said waste as fuel. The most used power plants are still coal ones and they are much worse ecologically than the nuclear ones. Not even mentioning that by burning coal, there are radioactive particles released into the air.

[@mode3763]

@@BloPsy__ So why does everyone wanna get rid of nuclear power and cover everything in PV panels?

[@BloPsy__]

@@mode3763 Because of the "very smart" people that fear the Nuclear energy. Germany is great example. They had shut down their nuclear power plants, yet their renewable energy sources aren't sufficient enough for the country. They are buying energy from other countries - that energy is mostly produced by coal and nuclear power plants. For example, Czechia is the one country that is selling it's energy to Germany. And Czechs do not want to shut down their nuclear power plants even tho there are a lot of protests from their neighbours. They even plan on upgrading the existing powerplants to get more energy, because they know that coal will once dry up and nuclear is only viable option in this part of the world. Solar panels are utopian dream that will cost huge amount of money and will pollute our planet a lot if everyone will really switch to that. Not even mentioning the need of some sort of energy storage for winters, bad weather times etc. It will be probably huge battery banks, which will only last for few decades since you know, batteries, that will pollute our world so much, that those "very smart" people will regret not trusting Nuclear energy.

[@JasonJrake]

Good points. LTO have less than half the Wattage-density and are lower voltage too. They also have a more stable voltage loss during discharge, which is great for output usage but makes measuring their charge percentage less accurate.

[@kayzinti4452]

@@kayzinti4452 I’ve seen that video and I’m not sure what you are referring to. The lowest listed nominal ratings i found online: for LTO is 2.4v, for LFP it’s 3.2v. Maybe cells arranged into 12+ volt stacks are higher voltage in LTO though, if that’s what you mean. The rule of thumb for lithium chemistries is that: As nominal voltage goes down, Discharge voltage slope flattens, Functional Temp range increases, Watt-hour density decreases, Safety increases.

and another advantage: LFP cells can operate 3.3 volt IC directly and without a voltage regulator. The voltage of 2.5 to 3.6 volts fits the circuits well. LIPO, on the other hand, have a voltage of up to 4.2 volts, which is too high for 3.3 volt circuits. The necessary voltage regulator dissipates energy into heat.

[@user-in3br2qs8x]

That doesn´t work. when batteries get older, they also lose voltage. Thus your LFP-cell no longer reaches 3.3 Volt, but e.g. 3.1 volt only for each cell. See? Or even 3 volts only. That is natural aging of batteries in general btw. so that is NOT an advantage, since you cannot use a device with batteries and put no voltage-regulator in it, without thinking over what happens when your battery reaches an age of e.g. 1 year or 5 years. This is when people mean a typical modern LiPo-battery will reach 80% of performance after about 1000 cycles. This means you lose 20% voltage as well. And this means, your battery no longer reaches 4.2 volts but instead (-20% => 10% = 0.42 volts here) you only get your battery to charge until 4.2 - 0.8 = 3.4 volts only. But this is in theory only, since each battery operates differently and normally each device uses multiple cells to reach higher voltages. So assuming you have a 3-cell setup (3 cells á 4.2 volts) = typical 12V-li-Po battery that means instead of reaching 12.6 volts, you now only reach about 12 Volts only. And 12 volts equals 80% of capacity here. At 10 Volts (equals 3.3 volts for each cell) your battery is at nearly 0% load so it´s EMPTY.

I've been telling people for years about the dangers of making a battery bank with Lipo batteries and those people looked at me like I was crazy. While LIFePo4 batteries will combust also. The chances of having an unpleasant reaction inside a structure is greatly reduced especially with a battery management system that can monitor the temperature and the individual charge on each battery in an array. The cases that house the electrolyte for LIFePo4 batteries are pretty resilient against physical damage. They are unlikely to be damaged unless someone uses a tomahawk like in the video or uses a wrench and physically short circuits the cells through stupidity. Remember a fuse is your friend, always use one of the correct rating. A breaker may not be so friendly.
